A U.N.-appointed panel of human rights experts says it has documented cases of unlawful killings, torture and abuses by Syrian government forces and anti-government armed groups.

The members of the Independent International Commission of Inquiry on Syria said in a report Thursday that since March the Syrian government forces have killed people unlawfully during anti-government demonstrations in Idlib, Homs, Aleppo, Hama, Damascus and Dara and in “numerous villages throughout the country.”

They also say that anti-government armed groups also have killed army and security forces and suspected informers that they have capture.
